STM32F429 Discovery - firmware update from USB drive

[MAlkh.1]

bootloader update the application saved on the USB memory stick attached to on STM32F429 Discovery board when reset occurs, it detects if USB flash memory pen is attached, if attached read and copy application file (hexfile) from usb and update

If reset happens or the board is powered up -> boot loader checks if usb flash memory is attached to the usb port , -> if attached-> check if there is firmware stored in the usb flash memory pen ->is so copy and update the application from usb stick-> then jump to the application which has been updated from the flash memory -> end.

Thanks I really appreciate of you can help me with this thanks.

I think this uses .BIN files, but could be adapted to handle .HEX or .DFU files.
